The set-up: Buster Posey homered for the fourth time in his last five games to give the Giants a 3-2 victory on Friday in a game that lasted 17 innings and took five hours and 28 minutes to complete. Te Reds won by a similar 3-2 score in the opener of this four-game series on Thursday and the teams continue the series this afternoon at AT&T Park. The Reds have had excellent success here in San Francisco lately, having won 15 of their last 21 games at AT&T Park. Cincinnati is 19-16 on the season, while the Giants' win still leaves them with MLB's worst record at 13-24. San Francisco's offensive woes continued last night (3.24 RPG ranks 29th) but the Giants have received a welcome spark from the leadoff spot in the past two games from center fielder Denard Span, who has gone 7-for-12 with a home run and three RBI in his return from the disabled list.

The pitching matchup: Lisalverto Bonilla (0-0 & 7.20 ERA) makes his first start of 2017 for the Reds and goes up against San Fran's Matt Moore (1-4 & 6.52 ERA). Bonilla hopes to be a steady replacement for struggling right-hander Rookie Davis, who was optioned to Triple-A Louisville after posting a 7.58 ERA in five starts. Bonilla pitched five innings of relief against the Cubs on April 22 before going back to Triple-A, where he went 0-2 with a 5.65 ERA in three starts. However, back in 2014 with Texas, he made five appearances, including three starts. He won all three of those starts, posting a 2.11 ERA. Moore's 2017 struggles continued in his last outing, this past Monday against the Mets. He allowed three runs in 5 1/3 innings while throwing 108 pitches. Moore has allowed five or more runs in four of his seven starts this season with San Francisco going 1-6 and minus-$ 581 against the moneyline. He will be facing the Reds for the first time in his seven-year career (most spent with Tampa Bay in the AL).

The pick :Both teams are hoping to see starting pitchers Bonilla and Moore work deep into Saturday's contest, after they combined to use 13 relievers in Friday's game. Bonilla has not made a major league start since 2014 and his 5.65 ERA in three starts at Triple-A hardly inspire confidence. Moore's overall stats look pretty ugly but on closer examination, while he owns a 10.50 ERA in three road starts this season, his ERA is 3.05 ERA in three outings at AT&T Park. Checking back to last year, Moore has gone 5-1 with a 2.51 ERA in his last eight home starts dating to August. Make the Giants a 10* play.
